播期与密度对沙地菊芋产量的影响

Effect on Date of Seeding and Density of Jerusalem artichock in Sand

本试验采用播期与栽培密度两因素的裂区设计,以确定沙地菊芋种植的较佳密度和适宜播期。研究表明,不同播期与密度交互作用对沙地菊芋地上部植株植物学性状无显著影响;而对于块茎性状及产量,春播优于秋播,密度以25500株/hm2为宜。

The assay use split plot design on two factors, including the date of seeding and density, to define the better density and most suitable date of seeding on sand Jerusalem artichoke. The result indicate that there were not dramatic influence of Jerusalem artichoke phytological trait on interaction of difference date of seeding and density. But for tuber trait and yield, seeding in spring is superior than fall, and the suitable density is 25500 plant per hectare.
